We enter fiscal 2012 with a large backlog, solid pipeline and confident of our ability to continue to execute against our strategic plan.”

Bottomline has presented supplemental non-GAAP financial measures as part of this earnings release. Core net income and core earnings per share are non-GAAP financial measures. The non-GAAP financial measures exclude certain items, specifically the fourth quarter release of a deferred tax asset valuation allowance, amortization of intangible assets, impairment losses on equity investments, equity-based compensation, acquisition-related expenses (including acquisition-related earn-outs) and restructuring related costs. The presentation of this non-GAAP financial information should not be considered in isolation from, or as a substitute for, the financial results presented in accordance with GAAP. Bottomline believes that these supplemental non-GAAP financial measures are useful to investors because they allow for an evaluation of the company with a focus on the performance of its core operations. Bottomline’s executive management team uses these same non-GAAP financial measures internally to assess the ongoing performance of the company. Additionally, the same non-GAAP information is used for planning purposes, including the preparation of operating budgets, and in communications with the board of directors in respect of financial performance. Since this information is not a GAAP measurement of financial performance, there are material limitations to its usefulness on a stand-alone basis, including the lack of comparability of this presentation to the GAAP financial results of other companies. Shares used in computing core earnings per share are calculated using the treasury stock method, which assumes full exercise of in-the-money stock options and warrants and full vesting of restricted stock. A reconciliation of the GAAP results to the non-GAAP results for the three and twelve month periods ended June 30, 2011 and 2010 is as follows:
